[0029] Example 1:

[0030] like Figures 1 to 3As shown, the adjustable filtration device for sewage treatment provided in this embodiment includes: a base 1; a filter cartridge assembly 2, disposed on the top of the base 1, including a filter cartridge 21, disposed on one side of the top of the base 1; a filtration module 3, disposed on one side of the filter cartridge 21, including an adjustment box 31, bolted to the outer wall of one side of the filter cartridge 21; and a discharge assembly 4, disposed at the other end of the top of the base 1, including a discharge cylinder 41, bolted to the other end of the adjustment box 31.

[0031] In this embodiment, the filter module 3 and the discharge assembly 4 constitute the adjustable filter device for wastewater treatment involved in this application.

[0032] It should also be noted that the wastewater treatment in this application can be municipal wastewater treatment (before and after secondary treatment), food processing wastewater (after pretreatment), circulating cooling water, etc. Figure 1 In this embodiment, wastewater treatment is described using food processing wastewater (after pretreatment) as an example. Of course, other types of wastewater treatment can also adopt a similar structure, which will not be elaborated on later.

[0033] In this embodiment, the base 1 has a rectangular structure made of high-strength steel, providing excellent stability and load-bearing capacity, and its surface is treated with anti-corrosion coating. The filter cartridge assembly 2 includes a filter cartridge 21, a cylindrical structure made of high-strength steel. Wastewater enters the filter cartridge 21 through the inlet 22, is filtered by the filter screen 326, and the filtered water is discharged from the outlet 23, with impurities trapped on the filter screen 326. The filter screen 326 can be replaced and adjusted by adjusting the assembly 32, and the flexible brush plate 42 scrapes away impurities from the filter screen 326, which are then discharged through the outlet 43. This provides efficient wastewater treatment functionality, ensuring the stability and adjustability of the filtration effect.

[0034] Specifically, the filter cartridge assembly 2 includes: an inlet 22, which is located at the top of the filter cartridge 21 and is connected to an external pipe with a flange seal, for injecting wastewater that needs to be filtered; and an outlet 23, which is located at the bottom of the filter cartridge 21 and is connected to an external pipe with a flange seal, for discharging the filtered water.

[0035] In this embodiment, the inlet 22 is a cylindrical structure used to inject the wastewater to be filtered. The outlet 23 is a cylindrical structure used to discharge the filtered water. Wastewater enters the filter cartridge 21 through the inlet 22, is filtered by the filter screen 326, and then the filtered water is discharged from the outlet 23. This ensures the smooth entry of wastewater and the smooth discharge of filtered water, improving filtration efficiency.

[0036] Example 2:

[0037] Based on Embodiment 1, in order to provide a flexible filter adjustment function, a filter module 3 is provided on one side of the filter cylinder 21.

[0038] Specifically, the filter module 3 includes an adjustment component 32, which is disposed inside the adjustment box 31.

[0039] As a preferred implementation, the filter screen 326 can be replaced and adjusted by adjusting component 32, ensuring the stability and adjustability of the filtration effect. It provides flexible filter screen adjustment functionality to adapt to different wastewater treatment needs.

[0040] Specifically, the adjustment assembly 32 includes: a handwheel 321, rotatably mounted on the top of the adjustment box 31; a dial 322, rotatably mounted inside the adjustment box 31, with the top of the rotating shaft bolted to the handwheel 321; a grooved wheel 323, rotatably mounted inside the adjustment box 31, and rotating in cooperation with the dial 322; a rotating rod 324, rotatably mounted inside the adjustment box 31, and bolted to the grooved wheel 323; a filter frame 325, rotatably mounted inside the adjustment box 31, and rotating inside the filter cylinder 21; and four sets of filter screens 326, located inside the bottom of the filter frame 325.

[0041] In this embodiment, the handwheel 321 has a disc-shaped structure. The dial 322 has a cylindrical structure. The grooved wheel 323 has a disc-shaped structure. The rotating rod 324 has a cylindrical structure. The filter frame 325 is made of high-strength steel. The filter screen 326 has a disc-shaped structure and is used to filter impurities in wastewater. Rotating the handwheel 321 drives the dial 322 to rotate. One rotation of the dial 322 rotates the grooved wheel 323 by one-quarter. The grooved wheel 323 drives the filter frame 325 to rotate by one-quarter via the rotating rod 324. The filter screen 326 inside the filter cylinder 21 rotates out through the groove in the middle of the filter cylinder 21, and the filter screen 326 adjacent to the inside of the filter cylinder 21 rotates into the filter cylinder 21. This provides a flexible filter screen replacement function, ensuring the stability and adjustability of the filtration effect.

[0042] Specifically, the four sets of filter screens 326 have different mesh sizes.

[0043] This configuration allows for the replacement of filter screens 326 with different mesh sizes by adjusting component 32, ensuring adaptability of filtration performance. It provides multiple filtration options to meet various wastewater treatment needs.

[0044] Example 3:

[0045] Based on Embodiment 2, in order to provide an efficient impurity removal function, a discharge assembly 4 is provided at one end of the top of the base 1.

[0046] Specifically, the discharge assembly 4 includes: a flexible brush plate 42, which is disposed at the top inside the discharge cylinder 41 and scrapes against the filter screen 326 at the bottom; and a discharge port 43, which is opened on one side of the bottom of the discharge cylinder 41 for discharging impurities.

[0047] The flexible brush plate 42 has flexible brushes at its bottom for scraping away impurities from the filter screen 326. The discharge port 43 is used to discharge the impurities. The flexible brush plate 42 scrapes away impurities from the filter screen 326, and the impurities are discharged through the discharge port 43. This provides an efficient impurity removal function, ensuring the cleanliness of the filter screen and the filtration effect.

[0048] In actual use, the user first connects the sewage pipe to the inlet 22 through flange bolts. Then the sewage enters the filter cylinder 21 from the inlet 22. The sewage is filtered through the filter screen 326 inside the filter cylinder 21. The sealing ring set on the filter screen frame 325 on the outer periphery of the filter screen 326 blocks the sewage from leaking out and intercepts impurities on the filter screen 326. Then it continues to flow to the bottom of the filter cylinder 21 and is discharged from the outlet 23. When treating different types of wastewater and using different mesh sizes of filter screens 326, the user turns the handwheel 321 before the wastewater enters the inlet 22. The handwheel 321 drives the dial 322 to rotate. One rotation of the dial 322 rotates the grooved wheel 323 by one-quarter. The grooved wheel 323 drives the filter screen frame 325 to rotate by one-quarter through the rotating rod 324. The filter screen 326 inside the filter cylinder 21 rotates out through the groove in the middle of the filter cylinder 21. The filter screen 326 adjacent to the inside of the filter cylinder 21 rotates into the inside of the filter cylinder 21. The filter screen 326 that rotates out rotates to the outside of the filter cylinder 21. At this time, the user can choose to directly replace the filter screen 326. At the same time, the filter screen 326 that rotates out inside the filter cylinder 21 rotates relative to the filter screen 326 inside the discharge cylinder 41. The impurities on it are scraped off by the flexible brush plate 42. The impurities fall into the discharge port 43. If a certain amount of impurities accumulate, the user can use tools to remove them.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
